WASTE-PIPE STRAVINER.

SPECIFICATION forming part of Letters Patent No. 738,726, datedSeptember 8, 19,03. i Application iled December 26, 1902. Serial No.136,612. (No model.)

To will whom it may con/cern,.-

Be it known that LALBERT E. LYTLE, a citizen of the United States,residing at Chicago, inthe county ofH Cook and State of Illinois,

have invented certain new and useful Improvements in Strainers forWaste-Pipes, of which the following is a specilication.

This invention relates to improvements in a strainer to be used inconnection with the io waste-pipes of sinks and other basins; and itconsists in certain peculiarities of the construction, novelarrangement, and operation of its parts, as will be hereinafter morefully set forth and specifically claimed.

I5 The principal object of my invention is to provide a strainer whichshall be of such construction that it will permit of the free escape ofWater from the sink or other vessel,

. yet will prevent the accumulation of bits of 1 2o papers, toothpicks,burned matches, coecz5 iiow, as is usually t-he case when the strainersheretofore in use have been employed.`

Other objects and Vadvantages of the in vention will be disclosed in thesubjoined vdey' scription and explanation.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanyingdrawings, in which- Figure l is aperspective view of a `portion of a sink and apart of the waste-pipethereof, showing my improved strainer in position.`

Fig. 2 is an enlarged central sectional view the different views of thedrawings.

A represents a portion of a sink, which may be of the ordinary or anypreferred construction and, as usual, is provided with a screwthreadedopening a, in which the waste-pipe B is secured. Surroundinglthe openinga 5o and on its lower surface the bottom of the sink or vesselA isprovided with a screwthreaded neck b to engage the waste-pipe and alock-nut b', used to more securely hold the waste-pipe in position. Theupper surface of the bottom of the sink or vessel A is usually formedwith a recess a' around the opening a to receive the ordinary perforatedand hat strainer plate, which, as is Well known,is secured in place bymeans of screws, 6o which soon become corroded and rusted to such anextent that they cannot be removed when it is desired to remove saidplate. I't is therefore one of the objects of my invention to provide astrainer which can be `easily detached to permit of it being cleaned,but when iu position for use will be firmly held against accidentaldislocation. The strainer consists of a balloon or pear shaped body C,having a series of perforations c andat its lower por- 7o tion a numberof upwardly-extending slots c', which preferably taper Vtoward theirupper ends. The tapered lower portion of the body C is provided with anannular iiange c2, which rests in the recess a', from which the ordi- 75nary strainer-plate has been removed, so as to be iiush with 'the uppersurface of the bottom of the sink. The lower surface of the iiange c2 isprovided with a neck c3, of any suitable length, to t within the upperpor- 8o tion of the waste-pipe B, thus further securing the strainer inplace and so as to prevent it tipping over. As shown in Fig. 2 of thedrawings, the neck c3 surrounds the opening c4 in the lower end of thestrainer-body. In 85 Fig. 3 of the drawings I have shown a modified formof the strainer, which consists in making it of two pieces C and C2instead of one piece, as shown in Figs. 1 and 2 of the drawings. Each ofthe -pieces C' and C2 is 9o provided at each of its sides with lugs CZ,through which are passed screws orfrivets d', used to hold the piecescomprising the strainer together. For the convenience of manufacture Iprefer to make the strainer of two pieces, but do not desire to belimited to such a construction. In Fig. 4 of the drawings is shown stillanother modification,which consists in omitting the ange c2 andalso theperforations c, yet employing the upwardlyextending slots c' and neck c3to fltin the upper end of the drain-pipe oropening inthe bottom of thebasin or Vessel.

From the foregoing and by reference to the drawings it will be seen andclearly understood that by using a strainer embodying my invention thewater will be allowed to escape at all times, and as it passes throughythe slots c the accumulations of the bits of paper,coeegrounds, andthelike will be caused to settle around the lower portion of the body byreason of its inwardly-tapered shape, thus preventing the openingsbecoming clogged, so as to cause overflow of the basin or vessel. It isalso apparent that the strainer may be readily removed when it isdesired to clean the same and easily replaced.

Having thus fully described my invention, Y

what I claim as new, and desire to secure by Letters Patent, is- A 1. Asan improved article of manufacture, a strainer comprising a perforatedbody portion tapered toward its lower part and pro- .vided at its lowerportion with an annular tending slots, an annulaiange on its lowerportion, and a neck on the lower surface of said flange, substantiallyas described.
